France coach Didier Deschamps says Matteo Guendouzi has transformed since leaving Arsenal.

The midfielder will sign permanently with Olympique Marseille at the end of the month.

Dedchamps has seen a visibly difference in Guendouzi this season.

"He is more fulfilled, more playing time, he has confidence in himself. It brings a lot of freshness, life, quality," he said.

"He's important."
